Secretion and excretion of endogenously synthesized lipids by adult Haemonchus contortus in vitro

Results of the incorporation of carbon from 14C-glycerol into total, polar and nonpolar lipids in Haemonchus contortus (Nematoda: Trichostrongylidae) reveal that the radioactivity lost into the medium as lipids decreased during the first 3 h of incubation. This was followed by a drastic increase during the 4th h. Again, there was a decline by 75% during the 5th h. However, there was a slight increase in the nonpolar lipids during the 5th h.
